Formats

Supported buffer and image formats may vary across implementations. A minimum set of format features are guaranteed, but others must be explicitly queried before use to ensure they are supported by the implementation.

The features for the set of formats (VkFormat) supported by the implementation are queried individually using the vkGetPhysicalDeviceFormatProperties command.

Compatible Formats of Planes of Multi-Planar Formats

Individual planes of multi-planar formats are size-compatible with single-plane color formats if they occupy the same number of bits per texel block, and are compatible with those formats if they have the same block extent.

In the following table, individual planes of a multi-planar format are compatible with the format listed against the relevant plane index for that multi-planar format, and any format compatible with the listed single-plane format according to Format Compatibility Classes. These planes are also size-compatible with any format that is size-compatible with the listed single-plane format.

Identification of Formats

A format is represented by a single enum value. The name of a format is usually built up by using the following pattern:

    VK_FORMAT_{component-format|compression-scheme}_{numeric-format}

The component-format indicates either the size of the R, G, B, and A components (if they are present) in the case of a color format, or the size of the depth (D) and stencil (S) components (if they are present) in the case of a depth/stencil format (see below). An X indicates a component that is unused, but may be present for padding.

Table 67. Interpretation of Numeric Format
Numeric formatType-Declaration instructionsNumeric typeDescription

UNORM

OpTypeFloat

floating-point

The components are unsigned normalized values in the range [0,1]

SNORM

OpTypeFloat

floating-point

The components are signed normalized values in the range [-1,1]

USCALED

OpTypeFloat

floating-point

The components are unsigned integer values that get converted to floating-point in the range [0,2n-1]

SSCALED

OpTypeFloat

floating-point

The components are signed integer values that get converted to floating-point in the range [-2n-1,2n-1-1]

UINT

OpTypeInt

unsigned integer

The components are unsigned integer values in the range [0,2n-1]

SINT

OpTypeInt

signed integer

The components are signed integer values in the range [-2n-1,2n-1-1]

UFLOAT

OpTypeFloat

floating-point

The components are unsigned floating-point numbers (used by packed, shared exponent, and some compressed formats)

SFLOAT

OpTypeFloat

floating-point

The components are signed floating-point numbers

SRGB

OpTypeFloat

floating-point

The R, G, and B components are unsigned normalized values that represent values using sRGB nonlinear encoding, while the A component (if one exists) is a regular unsigned normalized value

SFIXED5

OpTypeInt

scaled signed integer

The components are signed fractional integer values that get converted to floating-point in the range [-1024,1023.96875]

n is the number of bits in the component.

The suffix _PACKnn indicates that the format is packed into an underlying type with nn bits. The suffix _mPACKnn is a short-hand that indicates that the format has m groups of components (which may or may not be stored in separate planes) that are each packed into an underlying type with nn bits.

The suffix _BLOCK indicates that the format is a block-compressed format, with the representation of multiple pixels encoded interdependently within a region.

Table 68. Interpretation of Compression Scheme
Compression schemeDescription

BC

Block Compression. See .

ETC2

Ericsson Texture Compression. See .

EAC

ETC2 Alpha Compression. See .

ASTC

Adaptive Scalable Texture Compression (LDR Profile). See .

For multi-planar images, the components in separate planes are separated by underscores, and the number of planes is indicated by the addition of a _2PLANE or _3PLANE suffix. Similarly, the separate aspects of depth-stencil formats are separated by underscores, although these are not considered separate planes. Formats are suffixed by _422 to indicate that planes other than the first are reduced in size by a factor of two horizontally or that the R and B values appear at half the horizontal frequency of the G values, _420 to indicate that planes other than the first are reduced in size by a factor of two both horizontally and vertically, and _444 for consistency to indicate that all three planes of a three-planar image are the same size.

No common format has a single plane containing both R and B components but does not store these components at reduced horizontal resolution.

Representation and Texel Block Size

Color formats must be represented in memory in exactly the form indicated by the format’s name. This means that promoting one format to another with more bits per component and/or additional components must not occur for color formats. Depth/stencil formats have more relaxed requirements as discussed below.

Each format has a texel block size, the number of bytes used to store one texel block (a single addressable element of an uncompressed image, or a single compressed block of a compressed image). The texel block size for each format is shown in the Compatible formats table.

The representation of non-packed formats is that the first component specified in the name of the format is in the lowest memory addresses and the last component specified is in the highest memory addresses. See Byte mappings for non-packed/compressed color formats. The in-memory ordering of bytes within a component is determined by the host endianness.

Packed formats store multiple components within one underlying type. The bit representation is that the first component specified in the name of the format is in the most-significant bits and the last component specified is in the least-significant bits of the underlying type. The in-memory ordering of bytes comprising the underlying type is determined by the host endianness.

Depth/Stencil Formats

Depth/stencil formats are considered opaque and need not be stored in the exact number of bits per texel or component ordering indicated by the format enum. However, implementations must not substitute a different depth or stencil precision than is described in the format (e.g. D16 must not be implemented as D24 or D32).

Format Compatibility Classes

Uncompressed color formats are compatible with each other if they occupy the same number of bits per texel block as long as neither or both are alpha formats (e.g., VK_FORMAT_A8_UNORM_KHR) . Compressed color formats are compatible with each other if the only difference between them is the numeric format of the uncompressed pixels. Each depth/stencil format is only compatible with itself. In the following table, all the formats in the same row are compatible. Each format has a defined texel block extent specifying how many texels each texel block represents in each dimension.

Size Compatibility

Color formats with the same texel block size are considered size-compatible as long as neither or both are alpha formats (e.g., VK_FORMAT_A8_UNORM_KHR). If two size-compatible formats have different block extents (i.e. for compressed formats), then an image with size A × B × C in one format with a block extent of a × b × c can be represented as an image with size X × Y × Z in the other format with block extent x × y × z at the ratio between the block extents for each format, where

  • ⌈A/a⌉ = ⌈X/x⌉
  • ⌈B/b⌉ = ⌈Y/y⌉
  • ⌈C/c⌉ = ⌈Z/z⌉

For example, a 7x3 image in the VK_FORMAT_ASTC_8x5_UNORM_BLOCK format can be represented as a 1x1 VK_FORMAT_R64G64_UINT image.

Images created with the VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT flag can have size-compatible views created from them to enable access via different size-compatible formats. Image views created in this way will be sized to match the expectations of the block extents noted above.

Copy operations are able to copy between size-compatible formats in different resources to enable manipulation of data in different formats. The extent used in these copy operations always matches the source image, and is resized to the expectations of the block extents noted above for the destination image.

Potential Format Features

Some valid usage conditions depend on the format features supported by a VkImage whose VkImageTiling is unknown. In such cases the exact VkFormatFeatureFlagBits supported by the VkImage cannot be determined, so the valid usage conditions are expressed in terms of the potential format features of the VkImage format.

The potential format features of a VkFormat are defined as follows:

Required Format Support

Implementations must support at least the following set of features on the listed formats. For images, these features must be supported for every VkImageType (including arrayed and cube variants) unless otherwise noted. These features are supported on existing formats without needing to advertise an extension or needing to explicitly enable them. Support for additional functionality beyond the requirements listed here is queried using the vkGetPhysicalDeviceFormatProperties command.

Unless otherwise excluded below, the required formats are supported for all VkImageCreateFlags values as long as those flag values are otherwise allowed.

The following tables show which feature bits must be supported for each format. Formats that are required to support VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT must also support VK_FORMAT_FEATURE_TRANSFER_SRC_BIT and VK_FORMAT_FEATURE_TRANSFER_DST_BIT.

Format features marked {sym2} :normative{type="must"} be supported for optimalTilingFeatures with VkImageType VK_IMAGE_TYPE_2D if the VkPhysicalDevice supports the VkPhysicalDeviceSamplerYcbcrConversionFeatures feature.

Formats marked {sym3} do not require a sampler {YCbCr} conversion for VK_IMAGE_ASPECT_COLOR_BIT image views if the VkPhysicalDeviceRGBA10X6FormatsFeaturesEXT::formatRgba10x6WithoutYCbCrSampler feature is enabled.

Implementations are not required to support the VK_IMAGE_CREATE_SPARSE_BINDING_BIT, VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT, or VK_IMAGE_CREATE_SPARSE_ALIASED_BIT VkImageCreateFlags for the above formats that require sampler Y′CBCR conversion. To determine whether the implementation supports sparse image creation flags with these formats use vkGetPhysicalDeviceImageFormatProperties or vkGetPhysicalDeviceImageFormatProperties2.

VK_FORMAT_FEATURE_FRAGMENT_DENSITY_MAP_BIT_EXT must be supported for the following formats if the fragmentDensityMap feature is enabled:

  • VK_FORMAT_R8G8_UNORM

VK_FORMAT_FEATURE_ACCELERATION_STRUCTURE_VERTEX_BUFFER_BIT_KHR must be supported in bufferFeatures for the following formats if the accelerationStructure feature is supported:

This list of formats is the union of required storage formats from Required Format Support section and formats listed in shaderStorageImageExtendedFormats.

An implementation that supports VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT for any format from the given list of formats and supports shaderStorageImageReadWithoutFormat must support VK_FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT for that same format if Vulkan 1.3 or the VK_KHR_format_feature_flags2 extension is supported.

An implementation that supports VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT for any format from the given list of formats and supports shaderStorageImageWriteWithoutFormat must support VK_FORMAT_FEATURE_2_STORAGE_WRITE_WITHOUT_FORMAT_BIT for that same format if Vulkan 1.3 or the VK_KHR_format_feature_flags2 extension is supported.

An implementation that does not support either of VK_FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT or VK_FORMAT_FEATURE_2_STORAGE_WRITE_WITHOUT_FORMAT_BIT for a format must not report support for VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT or VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT for that format if it is not listed in the SPIR-V and Vulkan Image Format Compatibility table.

Some older implementations do not follow this restriction. They report support for formats as storage images even though they do not support access without the Format qualifier and there is no matching Format token. Such images cannot be either read from or written to.

Drivers which pass Vulkan conformance test suite version 1.3.9.0, or any subsequent version will conform to the requirement above.

Depth Comparison Format Support

If Vulkan 1.3 or the VK_KHR_format_feature_flags2 extension is supported, a depth/stencil format with a depth component supporting VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT must support VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_DEPTH_COMPARISON_BIT.

Format Feature Dependent Usage Flags

Certain resource usage flags depend on support for the corresponding format feature flag for the format in question. The following tables list the VkBufferUsageFlagBits and VkImageUsageFlagBits that have such dependencies, and the format feature flags they depend on. Additional restrictions, including, but not limited to, further required format feature flags specific to the particular use of the resource may apply, as described in the respective sections of this specification.
